The Study Of Information Interaction Of The High-Speed Railway Integrated Dispatching System Based On SOA

The high-speed railway integrated dispatching system is a complex large system, which integrates train operates dispatcher, transport planned management, power dispatcher, multiple units dispatcher, maintain and rescue and train, passenger service etc, and involves the transport organizations, locomotives and rolling stock, communication signal, power supply, security, monitoring, aintenance and rescue and other disciplines. Between the functional subsystems, amount of information transmission is large and the system interaction is complex. The problem effectively realizes the interoperability and information integration is one of the key about the construction of the high-speed railway integrated dispatching system.The architecture of integrated high-speed railway dispatching system is described and analyzed for each subsystem and interaction information between various subsystems. The traditional integration methods have some deficiencies, such as complex interface, poor expansibility, etc. Based on analysis of SOA principle and related technology about web service implementation, a new solution of system integration based on SOA was proposed.Using integrated electric dispatching subsystem as an example and based on J2EE technology, gave the detailed implementation about integration of various subsystem based on SOA which included service classification, service package using integrated development tools based on Eclipse, using lomboz plug-in to develop J2EE engineering, using Axis plug-in to develop Web Service, completed the service integration based on BEA Aqualogic Service Bus, Completed service calling by browser based on Struts technology.It has some reference meanings to the research and development of the high-speed railway integrated dispatching system of our country.
